There's a PRAM battery as well. Sorry, that's all I know.
This is an original Powerbook 100, with text files I've been needing to get out of it.
The battery is long since gone, I'd been retriving things periodically running it on the powersource. But awhile back it started giving me a low battery/10 second shutdown warning, and it goes to sleep. There is no battery in it.
I've hooked my powersource up to other Powerbooks and they work fine with it, other powersources on my Powerbook give the same warning.
Anyone know how to get this to boot up and stay up so I can retrive my files?
